INCOME TAXES

The "Tax Cuts and Jobs Act" (the "Tax Act") was signed into law in the first quarter of fiscal 2018. In the first quarter of fiscal 2019, we completed our accounting for the Tax Act and recorded an immaterial adjustment to income tax expense. We finalized the remeasurement of domestic deferred tax balances from the former 35% corporate tax rate to the newly enacted 21% tax rate and finalized our accounting for the global intangible low-taxed income tax, for which we elected the period cost method, and neither had a material impact on our consolidated condensed financial statements in the first quarter of fiscal 2019.

Our effective tax rate was 22.6% and (93.8)% for the first quarter of fiscal 2019 and 2018, respectively. The effective tax rates for the first quarter of fiscal 2019 and 2018 were impacted by state income taxes. Additionally, changes resulting from the remeasurement of deferred income taxes at newly enacted tax rates reduced the effective tax rate for the first quarter of fiscal 2018 by 118.1%. The effective tax rate for the first quarter of fiscal 2018 also includes a 2.3% benefit related to excess tax benefits associated with share-based payments to employees and a 1.8% benefit related to the domestic production deduction.

Unrecognized tax benefits were $296 million and $308 million at December 29, 2018, and September 29, 2018, respectively.

We estimate that during the next twelve months it is reasonably possible that unrecognized tax benefits could decrease by as much as $13 million primarily due to expiration of statutes of limitations in various jurisdictions.
